Al-geizawi laparoscopic auto-knot sutures device

ABSTRACT

The Auto-Knot Device will be used to make suture knots. Can be made of material not harmful to the human body. FIG.  2  shows the device with reference numbered arrows pointing to the components of the device. FIG.  7  shows the direction of movement of the suture thread ( 6 ) to make the knot and FIG.  8  shows the steps of making the knot. One surgeon using two needle holders will be capable of making a knot. Using the auxiliary thread ( 4 ) to adjust the device by rotating it clockwise and counter clockwise to the proper position to insert the suture thread ( 6 ) into the groove ( 1 ). As soon as the suture thread ( 6 ) is in the groove ( 1 ), he will complete the knot by pulling the suture thread ( 6 ) up and toward the end of the groove, while holding the auxiliary thread ( 4 ) in the opposite direction.

BACKGROUND OF THE INVENTION

Laparoscopic suturing and knot tying are considered the most difficultlaparoscopic skills to master. Many surgeons find difficulties in makingknots after suturing due to limited space during laparoscopic surgeryand since it is a technically demanding part of the procedure, inaddition to the time needed to make such knots, most surgeons requiretraining courses to be able to perform laparoscopic knots. The learningcurve requires performing many operations before a surgeon becomescomfortable in mastering these knots. This devise will save time withless training.

BRIEF SUMMARY OF THE INVENTION

An easy built-in knotting mechanism (auto-knot device) attached to theauxiliary thread that will allow the device to be adjusted to the properposition to insert the suture thread into the groove and secure the knotby pulling the auxiliary thread and the suture thread in oppositedirections to finish the knot. The device is two spheres fused together,one sphere has groove to secure suture thread and the other one has aknot to keep device in place a longer period of time during theabsorbant stage in case absorbable material has been used. This devicewill reduce the time required to accomplish the task of laparoscopicsuturing and knot tying by requiring only one surgeon to perform thesurgery (See FIG. 7-12, showing, in reduced scale, the steps of makingthe knot in the tissue using the device and needle holders). It willalso make laparoscopic knots feasible for right and left handed surgeonsand with fore-handed and back hand suturing. This device can be usedwith any size suture thread or any type of suture needle and can bemanufactured from any material that is not harmful to the human body.

DESCRIPTION

FIG. 1 is a top, front, and right hand side perspective view of theLaparoscopic Suturing Auto-Knot Device.

FIG. 2 is same as FIG. 1, but showing reference numbered arrows, 1-7;pointed at the components of the device; which is: 1—Groove, 2—Left-handSphere, 3—Knot, 4—Auxiliary thread, 5—Needle, 6—Suture thread, and7—Right-hand sphere.

FIG. 3 is a perspective view of needle, suture thread, and auxiliarythread with the knot in between, before fusion into device.

FIG. 4 is top perspective view of the device thereof;

FIG. 5 is showing bottom perspective view thereof;

FIG. 6 showing front perspective view thereof;

FIG. 7 is a top, front, and right hand side perspective view showingdirection of the suture thread being passed through the tissue, usingtwo needle holders, one holding the suture thread needle and the otherone holding the auxiliary thread in order to complete the knot bypulling the suture thread into the groove of the device.

FIG. 8 is a top, front, and right hand side perspective view showingstep 1—of making the knot by showing the suture thread being pulledforward throught the tissue in the direction of the arrows in order toput the device in place.

-   -   FIG. 9 is a top, front, and right hand side perspective view        showing step 2—of making the knot by showing the suture thread        being pulled backwards and the auxiliary thread being pulled        foreward both of them in the direction of the arrows.    -   FIG. 10 is a top, front, and right hand side perspective view        showing step 3—of making the knot by showing the suture thread        being rotated underneath the device, about 100 degrees        clockwise, in order to make the suture thread face the groove.    -   FIG. 11 is a top, front, and right hand side of perspective view        showing step 4—of making the knot by showing that the suture        thread has been pulled up and placed in the groove to start        rotating the device counter clockwise in the direction of the        arrows.

FIG. 12 is a top, front, and right hand side perspective view showingthe knot has been put in place and secured, by pulling the suture threadand the auxiliary thread in opposite directions to secure the suturethread at the end of the groove to complete the knot.
